[OpenMP][test] Define print_possible_return_addresses on SPARC (#138523)

Browse Source 
Parts of the `openmp` testsuite currently don't build on SPARC due to
the lack of a `print_possible_return_addresses` definition.

This patch provides one. With it, the vast majority of tests `PASS` on
Solaris/sparcv9 and, with an additional patch, on Linux/sparc64.

The current definition was obtained empirically.

Tested on `sparcv9-sun-solaris2.11`, `sparc64-unknown-linux-gnu`,
`amd64-pc-solaris2.11`, and `x86_64-pc-linux-gnu`.
